VICTOR E. HAAS, OF SYLVANIA TOWNSHIP, LUCAS COUNTY, OHIO, ASSIGNOR OF ONE- HALF TO SAMUEL E. STARR AND ONE-HALF TO WILLIAM E. WALDO, BOTH F TOLEDO, 01110.

Application filed June 21,

To all whom it may coacem- Be it known that I, Vro'roR E. HAAs, a

citizen'of the United States, and a residentf of Sylvania Township, in the county of Lucas and State of Ohio, have invented a certain new and useful Device for Carbureting Air; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appfltains to make and use the same, reference being bad to the accompanying drawings and to the characters of reference marked thereon, which form a part of this specification. My invention has for its object to provide a liquid fuel carbureting device that will cause substantially all of the liquid tobe atomized, and thus completely separate the liquid that will atomize at ordinary term peratures from the heavier hydrocarbon materials. It also has for its object to provide a means for thoroughly mixing the liquid at ordinary temperatures with air and at the same time giving full opportunity for the heavier liquids or material contained in the fuel to be separated out. I

'The invention may be contained in constructions of different forms that are within the scope of my claims. To show the practicability of my invention I have selected a construction as an example of constructions containing my invention and shall describe it hereinafter. The construction selected is illustrated in the accompanying drawings.

Figure 1 of the drawings is a side view of the carbureting device selected and Fig. 2

is a vertical sectional view takenithrough the axis of the carbureting device along the line i 2, 2indicated in Fig. 1.. I

The vcarbureting device 1 is provided with a cylindrical frame2 to which the other parts are directly or indirectly connected.

I Thecylindrical frame ,2 is provided with a "connector 3 to which a source of liquid fuel supply may be 1connected. The fuel passageway 34 communicating with the con-- 'nector" 3 terminates in a contracted area 4' that is controlled by the end 5 of the needle valve 6 which is operated by means of the head 7 to control the flow of the fuel into the carbureting device andalso to shutoff the '2 with it the liquid fuel.

fuel from the carbureting device- The fuel passageway 34 terminates in a vertical pas tical passageway 8. The upper end of the passageway 10 may be closed by meansof a threaded. plug 11. By this arrangement the air enters the carbureting device and passes to a point above the end '4 ofthe fuel passageway and thus moves downward by the end of thefuel passageway and carries This prevents the which might cause leakage from the carbureting device. 2

' A pipe 12 is connected to the frame 2 and communicates with the lower end .of the passageway'8. The lower end of the pipe 12 is connected to bottom 13 of the carbureting device. A cylindrical shell 14 is located intermediate .the bottom 13- and the frame 2.

The shell 14 may be connected to the frame 2 and the bottom 13 in any suitable way, but

- located intermediate the shell 14 and the frame 2 and bottom 13 The pipe 12 is threaded into a boss 16 formed on the bottom 13. The lower end of the recess in the boss16 is cut back to c form-an enlarged portion 17 thatis located below the pipe 12'. The boss 16 is also provided with a plurality of passageways 18 that extendupwards from the enlarged portion 17 of the recess formed in the boss 16.

A'shell or sleeve 19 is threaded onto the boss 16 and forms an annular chamber around the pipe 12. The lower end of the'sleeve 191s provided with a plurality of openings '20,"

that arelocated at the upper end of the boss 16. The chamber 35 formed within the shell 14 is'ffilled or partially filled with the liquid fueL'the gasolene passing from the passage way l down through the pipe 1.2 up through the passageways 18 and out through the openings 20. The passageway elmay then be closed by the operation of the pin valve 5 and the air allowed to enter the carbureting device. The air passes through the passageway 8 down through the pipe 12 and upward through the passageways 18. The liquid at the start is forced down through the pipe and up through the passageways lS und then as the liquid is utilized or is carried upward and out between the anie 2 and the flange it enters the space between the sl eve 19 and the tube 12 through the openm 20 formed in the lower end of the sleeve 1-.

The frame 2 is provided with a concave lens shaped surface 21 while the sleeve 19 is provided with a saucer shaped flange 22 whose edge is located within the edge of the concave surface 21. The concave surface 23 of the flange 22 faces the concave surface of the frame 2. The flange 22 may be connected to threaded sleeve 24-. that threads upon the upper end of the shell or sleeve 19 and thus the flange may be ad-- justed with reference to the con *e surface of the frame 2. The mm of air and easolene which is an enlarged cap that provides a suitable.

volume or space within the carburetiug device above the surface of the liquid fuel.

The cap is preferably in the form of a dome.

25. The dome terminates in a passageway 26. A suitable n axle or connector 27 communicates with the passageway 26 and a flexible pipe of suitable form may be connected tothe connector 27. A. blow pipe or other instrument requiring' the supply of vaporized and air mixed fuel may be connected through the pipe to the carbureting device.

In the operation of the carbureting device,

the air nnderpressure will thus be confined fora short period of time within the sleeve 19 and thoroughly mixed with the fuel contamed 1n the sleeve 19 while it is forcing it up through the sleeve .19 and impingingitself and the fuelagainst the concave sur face 21 and also implnging itself and the fuel against the cylindrical surface of the.

shelhle, meanwhile thoroughly mixing and I .aitomizing practically all of the liquid material and filling the carbureting device carried upward, through the sleeve 19 strikes the concave above the surface. of the liquid fuel with the atomized fuel and air, and as the air is forced into the carbureting device, the mixture passes up through the chamber 36 of the dome and out throu h the Jasand thus nothing but the mixture of vapor and air, or of the fuel in a finely divided state and uncharged with drops of gasoline and air will pass out through the oassa e way 26. Since the concave surfaces 21 and particularly,because of the relative lo- 1 t on of their ed es produce a downwardly directed spray ie less volatile portions of the hydrocarbon fuel will be directed back into the chamber and prevent any an vaporized fuelor any but the liquid fuel in a very finely divided state from passing up into the dmno25. l urt-hermorc, the mixture of air and fueh finely divided or vaporized entering the'dome shaped chamber before findin itsexit throu 'h the small.

opening 26 gives ample opportunity for the return of the heavier portions, or 1111- vaporized fuel or fuel which .18 not in a finely divided state, hack into the chamber 85. In the continued oieration the fuel.

that thus returned to the chamber 35,

subsequently enters through the openings 20 and .is again subjected to the moving current of air to form a mixture' of fuel and air which is sprayed from between the surfaces 21 and 23 previously set forth, Probably most of the air together with the finely divided fuel or vapor will pass immediately from the cone-shaped spray throng. ....he domev The sin-farms 21 and 52 being' so arranged as to direct the spray diagonally downward as distinct from laterally in the separation of less volatile particles and prevents the collection of liquid gasoline in the tubing that leads from the pipe 27. lllhisprevenitsa sudden spurt of flame from a burner that may be conneoted to the carhureting device since only vapor or finely divided fuelv thoroughly mixed with air will-;pass to the burner. The coact1on of the concave surfaces .to di-.

rect the unvaporized or the non-finely divided fuel downward and the large transverse -area afforded by the dome prevents any disastrous discharge of unvaporized or non-finely dividedfuel from. bureting device. I I I When all of the liquid material removable b r atomizationhas been separated from the liquid fuel that is allowed to enter .the chamber formed-by theshell 1d, the residue,

the heavy liquid .or material, is drawn 0E.

The bottom 13 is provided with an outlet the ail cars 530 which is controlled by the valve 31 that when opened, allows the heavier liquid to pass through the outlet 30.
